论毒品犯罪案件的证据

Application of evidence in drug-related criminal cases

毒品犯罪案件有许多不同于普通刑事案件的特殊性,毒品案件中的证据又具有相对的单一性,必须当场缴获毒品和毒资才能证实犯罪。本文结合缉毒侦查中的具体情况,强调办理毒品案件必须增强证据意识,要把握好破案的时机,适时取证;收集证据一定要十分仔细,获取的证据应做好固定保全工作,并特别注意取证的合法性;采用技术侦察手段须把握住一条底线:不得诱人犯罪;应正确运用推定规则判定"明知",对推定结论允许以确凿的事实予以反驳。

Drug-related criminal cases have peculiar features compared with ordinary criminal cases. In such cases, evidence is always unique and cannot be used for proving crime when drugs and drug-related cash are not collected on the crime site. This thesis, by taking into account the specific circumstances in the investigation of drug-related crimes, emphasizes the necessity in enhancing awareness of evidence and the time for collecting key evidence and other evidence. Precaution is a necessity in evidence collection. Collected evidence should be fixed in a certain form. Special attention should be paid to the legitimacy of evidence collection. When technical means is used for investigation, one bottom line should not be overstepped： no one is allowed to induce suspects into committing crimes. For ＂known＂ evidence, presumption rules should be properly employed and inference conclusion may be rebutted with the support of determined facts.
